Overview

Brandon Rhodes' PyOhio 2014 talk on applying the Clean Architecture in Python. He shows how this high-level design pattern fits Python's features and addresses maintainability problems in large applications.

On Hacker News

HN points to it as a practical way to separate business logic from I/O, which reduces mocking and underlies the functional core, imperative shell idea.

I'd really recommend this video. I had seen it years ago and just came back to it. It's about changing your architecture, one of the effects of that being changing how you need/use mock. [VIDEO]

"Promote I/O to management (where it can't do any damage)" is the actionably good thing i've taken from Brandon Rhoades' talk based on this: [VIDEO] Living in a world where people regularly write single functions that: 1. loads data from a hardcoded string path of file location 2. does all the analysis inside the same loop that the file content iteration happens in and 3. plots the results ... that cleavage plane is a meaningfully good one. The rest of the ideas fall into "all things in moderation, including moderation", and can and should be special-cased judiciously as long as you know what you're doing. But oh god please can we stop writing _that_ function already.
